Patent CA-2241538-A1 (CA)
Inventor: PRAGT JOHAN H
IPC: F23N5/06
Filed: 1997-11-13
Abstract: A valve unit provides low pressure unregulated gas flow and high pressure regulated gas flow to a burner and comprises a main diaphragm valve (4) and a bypass diaphragm valve (13) which are opened by pressure differentials on their respective valve diaphragms (9, 19). A regulator valve (26) and a snap valve (27) modify gas pressure applied to the main and bypass valves diaphragms respectively. A control means (28) actuates the regulator and snap valves based on degree of temperature deficiency sensed in a monitored space. The control means opens the snap valve (27) to provide unregulated gas flow when low gas pressure is required, and opens the regulator valve (26) to provide regulated high flow when high gas pressure is required.

Title: Method and apparatus for reducing the effect of rough sea surface conditions on marine seismic sources
Inventor: WALKER LEON JOHN
IPC: G01V1/02
Filed: 1997-01-15
Abstract: A method of and apparatus for controlling the operation of a multiple-element marine seismic pulse generating source in rough sea surface conditions is disclosed. The method first determines the shape of the path along which the elements are traveling at the point in time just before each element of the source is activated. Once the shape of the path is known, the relative vertical position of each element relative to a fixed reference is determined.  Adjustments can then be entered into the firing times for each element such that the primary pressure peaks constructively interfere with one another. In a preferred embodiment, a plurality of inclinometers associated with the harness from which the devices are suspended provides a tilt angle measurement from which the shape of the path can be determined and the firing times adjusted accordingly.

Title: Distributed fiberoptic ice detector (dfoid)
Inventor: DJORDJEVICH ALEXANDAR
IPC: G01N21/41
Filed: 1998-08-19
Abstract: This invention, called "Distributed Fiberoptic Ice Detector", (DFOID) detects an early formation of ice at multiple, distributed locations on surfaces it is attached to. DFOID may be thought of as a generalization of FOID (fiberoptic ice detector), an earlier patent (application CIPO# 2,048,991) by the same inventor. While FOID accomplishes ice detection at either (i) single or (ii) multiple (distributed) locations, DFOID is intended for the latter task such that the response from the individual, distributed detection-locations is equalized. Alternatively, instead of equalization, conformity to a pre-specified rule describing how the response should vary from one to another location may be achieved. Just like FOID, DFOID is also based on the light diffusion by ice and light reflection from ice boundaries that optically couple multimode optical fibres in specially built sensitive zones distributed along the fibre. A most widespread use of this invention is expected in the aircraft industry for remote detection of ice formation around critical parts - wings (and hinges of command surfaces in particular).

Title: Method of enhanced max-log-a posteriori probability processing
Inventor: HUNT ANDREW
IPC: H03M13/45
Filed: 1998-08-14
Abstract: The invention comprises an enhancement to max-log-APP processing that significantly reduces performance degradation associated with introducing the "m ax" approximation into log-APP computations, while still maintaining lower computati onal complexity associated with max-log-APP processing. This enhancement is achieved by adjusting extrinsic information produced by a max-log-APP process where the magn itude of the extrinsic information is reduced, for example, by multiplying it with a s cale factor between 0 and 1.

Patent CA-2251489-A1 (CA)
Title: Communications methods and apparatus
Inventor: TERRY JOHN BRIAN
IPC: H04L1/00
Filed: 1998-10-22
Abstract: Ethernet frames are communicated via a telephone line between master and slave modems using half duplex communication of data and control information to avoid collisions, data to be transmitted being buffered in each modem. Different communication modes, involving different transmitted symbol frequencies, modulation methods, and bits per symbol to provide different transmission rates, can be used depending on errors on the line. To reduce signal attenuation and interference both of which increase with increasing frequency, a lowest frequency communication mode is used for transmitting control information when there is no data in the buffer for transmission, whereas a higher transmission rate communication mode is used for transmission of data and control information when the buffer is not empty. The communication mode can also be adjusted in dependence upon signal to noise ratio, signal and noise energies being monitored by the modem receiver respectively during and in a quiet period immediately following each received signal burst. Changes especially to a higher transmission rate communication mode can be made selectively depending upon a monitoring in the quiet period by the modem receiver of noise in the higher communication mode, the relevant signal to noise ratio being determined from this and a stored signal level for this mode.

Title: In situ construction of containment vault under a radioactive or hazardous waste site
Inventor: CARTER ERNEST E JR
IPC: C04B28/04
Filed: 1997-12-05
Abstract: A method is disclosed for constructing, verifying and maintaining underground vaults that isolate and contain radioactive burial sites. The method employs a buoyant lift technique to isolate a block of soil (78) containing the contaminants (73) from the surrounding soil. Molten permeation grouts seal fractures (26) and increase the effective thickness of the barrier (25). An impermeable synthetic liner (105) is embedded in the vault to enhance the integrity of the system. The integrity of the vault is monitored by a system of sensors (48, 49, 50, 51) placed both inside and outside of the sealed vault. The method eliminates the need to excavate or drill in the contaminated areas. Leaks which may develop are sealed by jet grouting with molten permeation grout.

Title: Process for preparing environmentally stable products by the remediation of contaminated sediments and soils
Inventor: REHMAT AMIRALI G
IPC: A62D101/22
Filed: 1997-12-23
Abstract: This invention relates to remediation and decontamination of sediments and soils contaminated with organic and inorganic contaminants. Environmentally stable products are produced when certain additives such as calcium oxides are mixed with the contaminated materials. In the process, the mixture is heated to produce a molten reaction product with at least part of an excess amount of oxygen mixture or air continuously bubbled through the melt (16) in order to provide mixing and achieve high thermal destruction and removal efficiencies of the organic contaminants. The melt (16) is then quickly quenched in moist air, steam or water to avoid the transformation of the amorphous material into crystals. The inorganic contaminants such as chromium, nickel and zinc are incorporated and completely immobilized within the amorphous silicate network. The amorphous material can be pulverized to yield a powder which evinces cementitious properties by blending it with other materials to produce blended cements.
